Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"post processing algorithm" » "post modeling algorithm" (Expand Search), "post routing algorithm" (Expand Search), "post tracking algorithm" (Expand Search), "waste processing algorithm" (Expand Search), "wood processing algorithm" (Expand Search), "food processing algorithm" (Expand Search)
"element te algorithms" » "element de algorithms" (Expand Search), "element tree algorithms" (Expand Search), "element two algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element data algorithms" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("image processing algorithm") OR ("post processing algorithm"))) OR ("element te algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"image processing algorithm\") OR (\"post processing algorithm\"))) OR (\"element te algorithms\"))".
• Removing quotes may allow a broader search: (((( image processing algorithm ) OR ( post processing algorithm ))) OR ( element te algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("image processing algorithm") OR ("post processing algorithm"))) OR ("element te algorithms"))*.
